Disable Data Reduction on a NAS Volume
By default, after disabling data reduction on a NAS volume, data remains in its reduced state during subsequent read operations. You have
the option to enable rehydrate-on-read when disabling data reduction, which causes a rehydration (the reversal of data reduction) of data
on subsequent read operations.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, expand NAS Volumes and select a NAS volume.
4. In the NAS Volumes panel, click Edit Settings.
The Edit NAS Volume Settings dialog box opens.
5. Clear the Data Reduction checkbox.
6. Click OK.

FluidFS Data Protection
This section contains information about protecting FluidFS cluster data. Data protection is an important and integral part of any storage
infrastructure. These tasks are performed using the Storage Manager Client.
Managing Antivirus
The FluidFS cluster antivirus service provides real-time antivirus scanning of files stored in SMB shares. The antivirus service applies only
to SMB shares; NFS is not supported. The scan operation is transparent to the client, subject to the availability of an antivirus server.
Files are scanned when a client tries to read or execute the file.
The antivirus service consists of two components:
• Antivirus servers — one or more network-accessible computers running a supported third-party, ICAP-enabled antivirus application to
provide the antivirus scanning service to the FluidFS cluster.
• A FluidFS cluster antivirus scanning policy specifies file extensions and directories to exclude from scans, an antivirus scanning file size
threshold, and whether to allow or deny access to files larger than the file size threshold.
When an SMB share client requests a file from the FluidFS cluster, the cluster passes the file to an antivirus server for scanning and then
takes one of the following actions:
